+See `README.md` for the canonical table. As of this writing: **M0.5–M6 done plus the Tier 1 1.0-readiness items** (Whisper model caching, cover lookup `--cover` + `--auto-cover`, ACE integration `dpub a11y` / `--a11y`, parallel `dpub batch`, stable `--json` output, `--rights` flag, ffmpeg metadata preservation). All on `main`. **M7 (WASM)** and **M8 (1.0 release)** remain. The post-1.0 strategic bet per `.claude/plans/can-you-look-at-quirky-allen.md` is **daemon mode + batch v2**.
